Normal Distribution Calculator

This calculator for Normal distribution asks to enter three parameters:
the known mean of your distribution, its standard deviation and the
value you want to explore. In return, the outputs will be the frequency
and the probability of the value under study.

Normal
Distribution

The
shaded area represents the probability of "x’"
and its frequency is "y".

The
average frequency of a certain type of computers
in manufacturing is 2 GHz.
The known standard deviation is 0.02 GHz. If the frequency of
those computers is normally
distributed, what
is the probability that a computer runs between 2 GHz and 2.01
GHz?

Run the calculator below
and enter...

Enter mean: 2
Enter std. deviation: 0.02
Enter variable: 2.01

The output is

Frequency = 0.3521
Probability = 0.6915
